Questions & Step-by-Step Solutions

What is the role of the 5' cap in mRNA?
  • Step 1: The 5' cap is a special structure added to the beginning of mRNA.
  • Step 2: This cap helps the ribosome recognize the mRNA so it can start making proteins.
  • Step 3: The 5' cap also protects the mRNA from being broken down by enzymes in the cell.
  • Step 4: Without the 5' cap, the mRNA would be less stable and could be destroyed quickly.
